Razer is looking to change that with its Hydra motion controller which has been developed specifically for PC gamers. Unlike other console-based motion control systems, the Hydra uses magnetic tracking technology by way of a base station that emits a magnetic field that Razer says allows the exact location and orientation of the handheld controllers to be detected with millimeter and degree accuracy.
